Pentatonix, the a cappella group founded by Arlington Martin High grads Mitch Grassi, Scott Hoying and Kirstie Maldonado, has scored its first Billboard top 10 debut with PTX Volume 2, which was released Nov. 5. The album is No. 10 on the current Billboard 200 chart, with 30,000 in CD sales. It also debuted at No. 1 on the magazine’s Independent Artist Chart.

This is just the latest bit of news in a busy month for the group, which also includes Avi Kaplan and Kevin Olusola, who were recruited by Grassi, Hoying and Maldonado for season three of NBC’s The Sing-Off, which the group won.

The group just kicked off a European tour, and will begin another North American swing beginning Feb. 4 at Midwestern State University in Wichita Falls. A deluxe version of Pentatonix’s Christmas album, PTXmas, is due out Nov. 19, with new recordings of Little Drummer Boy and Go Tell it On the Mountain added to the track listing.

Pentatonix’s latest video, a medley of Daft Punk songs, has more than 13.6 million views on YouTube.

On Nov. 3, Pentatonix and violinist Lindsey Stirling won a YouTube Music Award for their cover of Imagine Dragons’ Radioactive. They were also recently featured on and as they prepare to go on a BC World News With Diane Sawyer and on HLN. Neither report addresses the group’s Texas roots, which is understandable, although it would have been nice if the reports had at least mentioned the singers’ names (or if Sawyer stopped calling them “The Pentatonix”). You can watch both videos below. They are also scheduled to perform in the Dec. 9 edition of The Queen Latifah Show, which airs at 2 p.m. weekdays on KTVT/Channel 11.
